“…Laryngeal EMG can provide useful data concerning muscle denervation and reinnervation, and serial EMG can be useful for monitoring recovery and establishing a reliable prognosis and treatment plan. 22 Patients with a suspected neuropraxia as the etiology of their vocal cord paralysis, as was suspected in this case, have the highest rate of recovery. A recovery rate of 71% at 2 years after onset has been demonstrated in this population.…”

A stridulous, dysphonic cry with no external signs of trauma is a unique and unusual presenting sign for physical abuse. We report a previously healthy neonate with unremarkable birth history and medical history who presented with stridor and hypopharyngeal perforation due to physical abuse. This case highlights the need for further evaluation for traumatic injuries in the setting of unexplained new-onset stridor and consideration of physical abuse in the differential diagnosis.

“…We found normal EMG recordings in both patients diagnosed with arytenoid dislocation. Early differential diagnosis of joint fixation cricoarytenoid or arytenoids dislocation is essential for further surgical management and satisfactory prognosis 12,14 . An interesting ascertainment in this study was that in a high number of cases (14 patients) the electrophysiological diagnosis was an on-going axonal loss and in a low number of cases (4 patients) reinnervation waves were present.…”

Clinical application of laryngeal electromyography – a point of view

In recent years, the clinical importance of laryngeal electromyography (LEMG) has been recognized. This method of investigation proved itself to be a valuable and indispensable tool regarding voice disorder management and requires multidisciplinary approach. In this article, we focus on the clinical usefulness of LEMG to assess inferior and superior motor neuron integrity by recording action potentials generated by muscle fibers of the larynx in the new field known as neurolaryngology. To facilitate the clinical application of this electrophysiologic test, we present a detailed description of LEMG techniques, which were applied for simultaneous bilateral recordings of the thyroarytenoid, cricothyroid and posterior cricoarytenoid muscles. Also, we analysed and measured the following electrophysiological parameters: 1) insertional activity; 2) spontaneous activity; 3) recruitment; 4) morphology of waveform. From a practical point of view, in our country, LEMG performance is still not a routine procedure in ENT and Phoniatric Departments. The difficulty of practical use of LEMG in Romania consists in technical limitations and it depends on the physician’s experience regarding the examination technique and also the interpretation of electrophysiological results. Our current clinical experience shows that the use of LEMG contributes especially to the diagnosis, prognosis and treatment of patients with neurolaryngological disorders.

“…From the perspective of the conditions of testing, with the exception of the study by Ysunza et al, 11 who tested cooperative older children in the awake state, all studies used LEMG in the operating room under general anesthesia. Regarding the specific anesthesia protocol, the latest 3 studies (by Scott et al, 3 Jacobs and Finkel, 8 and Maturo et al 12 ) abandoned the previously used inhalational technique, which potentially can affect laryngeal movement, and used intravenous agents, allowing better control of the duration and depth.…”

“…The study by Koch et al 6 remains the only one to propose a 5-point scale of the LEMG findings; however, it was never validated or used again. None of the studies took to testing the diagnostic accuracy of LEMG except the analysis by Ysunza et al, 11 which purported near-perfect sensitivity (100%) and specificity (92%). Further, serial measurements over time were performed only in the latest 2 studies by Scott et al 3 (4 patients) and Maturo et al 12 (8 patients), but there was no longitudinal follow-up at equivalent times for all patients included.…”
